Roadway Calculator

Inputs explained

• Roadway Length (ft) — The length of the road or driveway in feet.
• Roadway Width (ft) — The width of the road or driveway in feet.
• Base Material Depth (in) — How deep the compacted base layer should be, in inches.

Understanding the result

Example: A 100 ft × 12 ft driveway with a 6-inch base needs about 22 cubic yards of material.

Frequently asked questions

Why is the base depth measured in inches while length and width are in feet? Base material depth is conventionally specified in inches because it's a much smaller dimension than the roadway's footprint; the calculator converts inches to feet internally before computing cubic yardage.

Does the estimate account for material compaction? No — it calculates the raw volume needed to fill the specified depth; compacted base material is typically ordered with 10-15% extra to account for settling, which isn't built into this base figure.

Is the Roadway Calculator free to use? Yes — it is completely free, with no sign-up, no download and no usage limits. You can use it as often as you need.

Is my data private? Yes. The calculation runs entirely in your browser — the values you enter are never sent to our servers, stored or shared with anyone.

What information do I need? Just the following: Roadway Length (ft), Roadway Width (ft), Base Material Depth (in). Each field includes a hint explaining exactly what to enter.

Can I use it on my phone? Yes — the tool is fully responsive and works on any device, and the same calculator is available in the EasyWorkCalcs mobile app.
